Description:SOFT COPY ATTACHED , Claims:WE CLAIM:

1. A communication system (200) configured to support a plurality of frame formats used for wireless communication, comprising:
a base station (203); and
a communication terminal device (202) configured to wirelessly communicate with the base station (203),
wherein numerologies that specify subcarrier spacings are configured respectively to the plurality of the frame formats, and
wherein synchronization signals and broadcast channels are mapped to common resources common to the plurality of the frame formats.

2. The communication system (200) according to Claim 1, wherein the common resources for the synchronization signals and the broadcast channels are statically determined based on standards.

3. The communication system (200) according to Claim 1, wherein the common resources for the synchronization signals and the broadcast channels are configured based on correlation with a timing for each of the frame formats.

4. The communication system (200) according to Claim 1, wherein timing information used for receiving each of the frame formats is included in the broadcast channels transmitted on the common resources.

5. The communication system (200) according to Claim 1, wherein sub-broadcast channels that carry additional information for the broadcast channels transmitted on the common resources are provided.

6. The communication system (200) according to Claim 5, wherein, as the additional information, information related to frequencies of the frame formats is carried in the sub-broadcast channels.

7. The communication system (200) according to Claim 5, wherein information related to frequencies and times for the sub-broadcast channels is carried in the broadcast channels transmitted on the common resources.

8. A base station (203) in a communication system (200) comprising the base station (203) and a communication terminal device (202) configured to wirelessly communicate with the base station (203),
wherein the communication system (200) supports a plurality of frame formats used for wireless communication,
wherein numerologies that specify subcarrier spacings are configured respectively to the plurality of the frame formats, and
wherein synchronization signals and broadcast channels are mapped to common resources common to the plurality of the frame formats.

9. A communication terminal device (202) in a communication system (200) comprising a base station (203) and the communication terminal device (202) configured to wirelessly communicate with the base station (203),
wherein the communication system (200) supports a plurality of frame formats used for wireless communication,
wherein numerologies that specify subcarrier spacings are configured respectively to the plurality of the frame formats, and
wherein synchronization signals and broadcast channels are mapped to common resources common to the plurality of the frame formats.
